8.6.5 Setting Purging
Purging is to remove condensed water in the calibration gas pipe by supplying a span calibration
gas for a given length of time before warm-up of the detector. This prevents cell breakage during
calibration due to condensed water in the pipe.
Open the solenoid valve for the automatic calibration span gas during purging and after the purge
time has elapsed, close the valve to start warm-up.
Purging is enabled when the cell temperature is 100°C or below upon power up and the purge
time is set in the range of 1 to 60 minutes.
